Initiate Public Bidding Process and Setting Date for a Public Hearing
(Project ID: 5581500006)
INTRODUCTION
This memorandum requests the City Council authorize initiating the bidding process and
set a public hearing on August 19, 2024, for the Old Mill Road Lift Station and Force
Main Project - Phase I.
BACKGROUND
The older sections of the Catfish Creek Sanitary Sewer (CCSS) that deliver wastewater
to the Catfish Creek Pump Station (CCPS) were constructed circa late 1960s. It is
common for sanitary sewer pipes to remain in service for 60 years or longer. However,
when sizing an interceptor sewer, it is not common to design it to handle predicted flows
more than 50 years into the future, most often a 25-year timespan is considered. The
CCPS was last upgraded in 1995 based on predicting growth over the next 20-30 years,
consistent with a 25-year life for a lift station.
Despite challenges due to terrain (i.e. steep slopes, bluffs, shallow rock, etc.), the City
has experienced significant growth within the Catfish Creek sewer shed in the last 20
years. Based on land use mapping in GIS, and only considering development that has
occurred over the last twenty years, within the tributary area, the design flow to the
CCSS and the CCPS has grown by 6.5 MGD (million gallons per day) since the pump
station was last upgraded in 1995 to a capacity of 8.0 MGD.
Due to potential development area within the CCSS tributary area, the City hired Strand
Associates, Inc. (Strand) in late 2018 to develop a better understanding of the hydraulic
capacity of the Catfish Creek Sanitary Sewer collection system. The analysis of the
CCSS and the CCPS involved the implementation of a flow metering program and the
development of a sanitary sewer model. One of the things that the computer model
revealed is that some wet weather events will result in the flow rising above the top of
the pipe, at certain locations, such that the sanitary system becomes pressurized which
is an indicator of possible SSO's
In late December of 2020, Strand provided the City with final drafts of both the study, for
Catfish Creek Sanitary Sewer collection system, and a more focused technical memo
which evaluated the effect of adding new industrial flow to the existing system.
On January 4, 2021, a State Revolving Fund (SRF) Planning and Design Loan Intended
Use Plan (IUP) application in the amount of $350,000 was submitted to the State for the
"Catfish Creek Lift Station & Force Main Project (that) involves system improvements to
address wet -weather related overflows at the Catfish Creek Lift Station and provide
capacity for future development within the Catfish Creek sewer shed".
On April 28, 2021, the City authorized Strand Task Order One, which provided for the
development of a facility plan and design of the Old Mill road lift station to a 30% level.
This level of design provided the City with a basis of design, a refined cost estimate,
and the necessary information to allow the City to submit a facility Plan to IDNR to begin
the SRF construction loan process. The 30% design followed the recommended
improvement option identified in the January 7, 2021, memo regarding the results of the
Catfish Creek Sanitary Sewer Interceptor system study, which evaluated the existing
system capacity and identified improvements to ensure that it has adequate capacity for
existing developments and for growth throughout the tributary area.
The City of Dubuque submitted a facility plan to Iowa Department of Natural Resources
(IDNR), in May of 2021, for the construction of a 20 MGD sanitary sewer lift station and
30" dual force mains. The facility plan is based on the results of an intensive evaluation
of the existing interceptor collection and pumping systems that transport sewage to the
Water Resource Recovery Center (WRRC). Several options were considered, and the
City chose to proceed with the design and construction of the Old Mill Road Lift Station
and Force Main Project, a recommended option. At the June 7, 2021, the City Council
meeting, the City Council approved the facility plan and IUP application for the Old Mill
Rd. Lift Station and Force Main Project.
Through the RFP process, Strand Associates, Inc (Strand) was selected and in
February of 2022, the City entered into an agreement with Strand Associates to
complete the final design of; the lift station, force main structures, modifications to
WRRC headworks, assist City staff with bidding services and with railroad permitting for
the horizontal bores under the railroad tracks. City Staff provided the site and utility
design for the remainder of the project, along with all coordination with IDNR and
property acquisitions.
Part of the SRF process is to complete an environmental review for the effected project
area, which is conducted by IDNR staff along with other state agencies. One of the
items that is looked at is the history of the area to determine the historical significance of
the area, if any. The Office of the State Archaeologist (OSA) conducted a phase
archaeological study, due to a portion of the project alignment running through the old
Town of Rockdale. Some artifacts, from the settlement, were recovered and it was
determined that a more in-depth phase II study was warranted. OSA and the State
Historic Preservation Office (SHPO) directed the City to complete a Phase 11
archeological study. Due to the results of the phase II study, it was determined that an
alternate alignment needed to be evaluated to avoid the Town of Rockdale. Once the
alternate alignment was selected, a second phase II archeological study was completed
for the alternate alignment. The alternate alignment was cleared by SHPO and the
design was able to be completed for the entire project.
Due to available funding and the funding being spread over five fiscal years, a revised
facility plan was submitted in May of 2024, that split the project into two phases. The
first phase being the lift station and site development and the second phase being the
force mains, from the lift station to WRRC, along with the force main structures. The
revised facility plan was approved by IDNR in June of 2024. The phased approach
allows the City to begin with the longest duration portion of the project, with currently
available funding, and start the second phase of the project a year later, when the
remainder of the funding becomes available in FY26 and FY27. The second phase will
be completed prior to the first phase completion.
DISCUSSION
The Old Mill Road Lift Station and Force Main Project is the first of several
improvements that are needed, within the Catfish Creek Interceptor Sewer system, to
provide adequate capacity to serve existing development, within the City, and to allow
for additional flow from future developments and the growth of the City.
Once constructed and in service, the 20 MGD Old Mill Road Lift Station will intercept
over 80% of the flow which currently goes to the 8 MGD Catfish Creek Lift Station. With
the reduction in flow coming from the Catfish Creek Interceptor System (West end of
town), the Catfish Creek Lift Station will then be primarily dedicated to the Key West
area and the growth areas along US Highway 151/61 to the airport which is served by
the Granger Creek Interceptor Sewer. Currently, IDNR has issued sanitary sewer
permits with peak flows totaling approximately 3.5 MGD, for the areas south of town,
since 2017. The reduction in flow from the Catfish Creek Interceptor System will
provide the Catfish Creek Lift Station with enough capacity to adequately serve the
sewer shed into the near future.

basis of design for the entire project. The remainder of the design for both phases is
funded utilizing ARPA funding. The construction administration and construction
engineering for phase I will be funded through an SRF construction loan. Both phases
of the project have been funded over multiple fiscal years, FY22 thru FY27. Phase I has
a completion date set for December of 2026. Due to the cost and duration of phase I, a
portion of the funding from the FY26 budget is being utilized as shown below.
The Old Mill Road Lift Station and Force Main Project - Phase I is utilizing the SRF loan
